Grinding automation and intellectualization

Grinding automation and intellectualization

  With mechanical manufacturing in FMS (flexible manufacturing system) andCIMS (computer integrated manufacturing system), IMS (intelligent manufacturing system) height automation development direction, the grinding automation requirements are put forward. The development of the CNC grinding machine with CNC lathe, milling machine and so on started late. In the 1980 s and 90 s is a CNC grinding machine for rapid development and entered the popularizing period of practical. Cnc machining In recent years, almost all kinds of grinder CNC products, CNC tool grinding machine from 3 to 10 shaft axis development. Which can realize online measurement, automatic switching of grinding wheel and the emergence of the automatic unloading workpieces milling machining center, mark CNC grinding reached a new level. Grinding CNC system development also have great progress, many special grinding CNC software and systems have been commercialized. In the 1990 s, Japan announced about intelligent grinding results. Use of monitoring information and database, adaptive optimization in grinding condition and the judgment condition of grinding, using computer simulation and virtual technology, establish a realistic virtual grinding environment, to implement the intelligent of the grinding. Continuous track the use of grinding technology, making the grinding technology has made great development. 

   Grinding process monitoring and detection technology

  Implementation of intelligent computer control of grinding, grinding process is an important problem in the control room. Solve the grinding process, such as the phenomenon of signal identification, signal sampling, signal processing, feedback and compensation, need high sensitive sensor, also need to have expert system or intelligent system and the software design and other technical support.For grinding wheel wear and tear of using acoustic emission monitoring system. Because of the complexity of the grinding process, the grinding process of the monitoring system in theory and practical aspect still has many problems unsolved. Parts after the grinding size, Cnc machining shape and position accuracy, surface quality of the test is divided into offline and online detection.For super precision grinding and free abrasive machining high precision and low surface roughness obtained after detection, high-precision grinding on the surface of the on-line automatic detection are much harder than cars, milling, high sensitivity is the key to development of sensor technology and signal acquisition, recognition and processing technologies.

   Software of grinding technology 

 High performance CNC grinding machine should be equipped with a complete software system. Of intelligence information processing and data input of grinding, grinding mode selection and grinding the arrangement of the order, condition of grinding, grinding wheel dressing and grinding automatically selected, the state of the grinding process simulation and virtual detection and compensation,Cnc machining  are in software design and development of a reasonable solution.All countries in the development of expert system and intelligent system software. Expert system is a branch of artificial intelligence research, and its essence is a kind of application system. Problem solving ability with expert level in the field of grinding process system, can effectively solve complex problems in the field of grinding.
